The eMMC on Zoom2 has an issue with respect to detection as a high capacity
card. This was discussed on the list with Pierre sometime back. I don't have
an acceptable solution to make this device work. Rather I prefer to submit a
patch which disables MMC2 on these boards.
You can still use MMC1 to mount your file system. This is the card you can
plug in to the cage.
